Description
The 13.5″ front torsion arm, pocketed to shed weight while keeping material where the load actually goes. This length fits all leading 600 Micro Sprint chassis manufacturers.
The torsion arm delivers the torsion bar rate to the corner, which makes it load-critical rather than a bracket. Arm length is also a setup variable – it changes the effective rate the corner sees.
This is the left front length. Pocketing saves unsprung weight at the front where it matters most. Bent one in a flip? Running a tweaked arm is how a good setup goes mysteriously bad. Built in Fresno, CA.
